Not sufficent permission to access « WordPress MU Forums

Hi, I have registered for a Sensualwriter blog :

of course it says that it cannot be found because after activating it, I could not even log in to create a post.

Even when I go to Sensualwriter.com and click log in, it gives me this same error :

You do not have sufficient permissions to access this page.

The account that I can not get into to post, is http://www.flirotica.sensualwriter.com

and that's not the only one. I have another account, with a different url, http://www.mistressalexis4u.sensualwriter.com

But, I simply cannot login to sensualwriter at all without getting that same 'permission to access' messege.

I even put my activated account name 'flirotica', before 'sensualwriter' in this url. Still nothing.

I even logged out of Wordpress and tried to access sensualwriter and still nothing :(

I have never downloaded any files for Sensualwriter, so it straight from the site. Can anyone advise?

Thank for the replies in advance!
